An example of finding the equation of a line in 3 dimensions. This video illustrates the general method you can always use to find the equation of a line.
@@gsuryasharon7703 yes but no, as normal vectors or trying to prove something is perpendicular uses the same process as finding a determinant. A determinant produces a scalar value while cross product produces a vector value
Thank you so much for the effort you put into your work. You’ve really helped me
You are a legend, God bless you.
Legendary teacher and channel
thank you sir....thanks very much
I really learned a lot about vectors
With cross products you subtracted j part but added the k part. Why?
Thisisaclevernameno He found out the determinant of the matrix.

why is J negative
Emily Hughes Look at finding the determinant of a 3x3 matrix
Take a look at finding the determinants of 3x3 matrices
It is because of finding the cofactor of the minors of the matrix. Look further into that and it'll give clarity.
@@kempossible02 finally I can solve this maths problem
@@emilyhughes4297 I was mostly writing it for people coming after and having the same question
Very bad that you didn't explain why you subtracted j, while added k !!
